... By definition a switch filters or forwards frames based on MAC addresses. This makes a switch a layer 2 device. Now we have layer 3 switches which have routing capability. If a data frame can’t be switched it is routed. Each port is a separate LAN port, but the forwarding engine actually calculates ...
